To JZ whom t may concern Be it known t atl, CHARLES S. WOOD,-

M.

vl l) respectively, curved lon itudinally. H is the outer casing of the evice made by me of strong canvas. The side edges of the easing H are secured rmly in place between base F and sub-bases G, G1, respectively, as by the screws I joinin said base F and subba (i1 together in Flgs. 1 and 2 and bolts I1 with nuts I2 thereon, in Figs. 3 and 4.

J, Fig. l, is a nipple secured in'one end of the casing H, und J1 is a cup covering nipple J. K is a pipe which,` in the preferred construction of the device, extends entirely through the casing H und to which the ends of said casing are secured as by wire or cord in the same manner as said ends are secured to the nipple J in the construction illustrated in Figs. 1 and 2. K1 is a cap on one end of pipe K which is removed when u pipe from a source of steam supply is to be attached to the device. K2 is a reducer which is attached to the discharge end of pipe K and if is a. drain pipe extending through reducer K and to near midway of pipe K1. The drain pipe It is provided with u stop cock la? in the usual manner and when water collects in pipe K in the use of the device, it is discharged therefrom on the opening of said stop cock, through the-drain pi e k. L represents a sand filling of cham The filling L is put :into the casing tlncugh the nipple J in the construction illustrated' in Fig. 1, after removing cap J1. In the construction illustrated in Figs. 3, 4 und 5, said 'sund filling is put into said casing after the pipe K is inserted therein and before the' ends of said casing are attached to said pipe as by Wire or cord k1. Chamber -B being well filled with said material (preferably Sand), the face of the device which cornes in contact with the inner face of the automobile eusing, when said device, casing and mold are assembled, as in Figs. l, 2 and 3,' is what I term yieldingly rigid. The yield ingly rigid character of said face ofthe device is comparable with that ofcasing X, when in position on the rim of a wheel with an inflated tube therein. The yielding fnnction of the face of the device is toudapt it to use in more than one size of casing and further to cause said face to lit closely to any roughness, as a lump, ridge, or patch on the inner face of an automobile casing,

er B of the device.

while at the same time its rigidity isJ such that when the device, an automobile casing and a mold are assembled and forcibly brought together by clamps M, the tire casing X is held firmly to the mold A and cas ing H is held firmly to the inner face of casing X.

I have termed the construction illustrated in Figs. 1 and 2, a modification because in prising un external base adapted to' resist pressure, means to apply pressure tosaid base, a flexible casing, and means to attach 'said casing to said base, in combination with a steam chamber and granular filling surrounding said chamber in said casing, said chamber provided with un aperture at its ends, and means to close said apertures, said base, Vsteam chamber and casing curved longitudinally, and said casing curved laterally.

2. A pad forvulcanizing tire casings comprising ay base curved longitudinally, a Hex ible casing, curved laterally, a sub-buse, means to attach said sub-base to said base with the sides of said casing interposed between said base and sub-base, a steam cha-mber in said casing, and a granular filling between the walls of said steam chamber and said casing.

3. A pad for vulcanizing tire casings. consisting of a hase and a casing made of fabric, in'combinaton with a sulrbase, means to attach said buse und sub-buse together with the casing interposed between them, a walled chamber in said casing, said chamber provided with un inlet, said casing adapted to form the laterally curved wall of an additional chamber, and a. illin in. said additional cliamber, to embed sait walled cham!` ber therein.
